Because you have 9 tiles in total, at first she has a 4 out 9 chance that she will turn over a tile with plants on it. Next she removed one so this means she has a 3 out of 9 chance of getting a tile with a plant on it. In percentage she will have a 33% chance of picking a tile with a plant on it .

Answer: (x+1)(3x+2) , i only got the answer for the first question, sorry!
Step-by-step explanation:
- factorise using AC method
AC= 3 x 2 = 6
find 2 numbers that add to give 5 and multiply to give 6 (3 and 2)
- put them as x in the equation to replace 5x
3x^2 + 2x + 3x + 2
- split the equation in half and expand each side
3x^2+2x | 3x+2
x(3x+2)+1(3x+2)
- put the numbers outside the brackets into a separate bracket
= (x+1)(3x+2)
